My skin is so dry that my makeup flakes off. Help!

—Haley Shook, Tempe, AZ

Bobbi: My derm suggested a solution and it really works: layering on moisturizers. I apply a lightweight hydrating cream, then I top it off with a thicker moisturizing balm.

Lightweight lotions are water-based, so if you follow them with a thicker cream, the heavier product will help seal in the moisture from the first lotion. Revive your foundation throughout the day by dabbing on a fast-absorbing face oil.

Next: I'm in my 30s and already seeing age spots on my hands. Are they permanent?
